ADA4077-2 4 MHZ, 7 NV/√HZ, low offset and drift, high precision amplifier
The ADA4077-2 is a dual amplifier with very low offset voltage, low drift, low input bias current, noise, and power dissipation. The output is stable with capacitive loads above 1000 pF without external compensation.
Applications for this amplifier include sensor signal conditioning (e.g., thermocouples, RTDs, strain gages), process control front-end amplifiers, and precision diode power measurement in optical and wireless transmission systems. The ADA4077-2 is suitable for line-powered portable instrumentation, precision filters, and voltage or current measurements and level settings.
Unlike competing amplifiers, the ADA4077-2 is specified over the extended industrial temperature range of −40°C to +125°C, and the MSL1 is specified for the most demanding operating environments. The device is available in 8-pin SOIC (including Class B) and MSOP (Class A only) packages.
